[mkgmap-dev] [Patch v1] improve mdr7 index

Thu Apr 13 07:39:02 BST 2017

Hi Carlos,

my idea was to use brackets in the label produced by the style , something like "ABC Road (grade1 (3m))"
Everything after the opening bracket is ignored by the --x-split-name-index option.
You can put the option into a file if the commandline causes trouble with special characters.

Gerd

Hi Gerd
I see the point about original OSM data, that's no problem.
If I use brackets I get an error:
bash: syntax error near unexpected element `('
I tried --x-mdr7-del=GRADE1(3M) and --x-mdr7-del=GRADE1 (3M)
May be it works in Windows.
